Open source foundation
Being based on an open-source project, users can inspect the code, contribute improvements, or customize the underlying scraping logic to fit specific needs.
OpenSERP combines multiple major search engines behind one API, making it easier to build reliable AI, SEO, and automation workflows without maintaining complex scraping infrastructure. Unlike many SERP APIs, OpenSERP is open-source, transparent, flexible, and designed for developers who need control, extensibility, and multi-engine coverage.
Developers, AI/LLM applications, automation platforms, SEO tools, researchers, and data teams that need search engine results from multiple providers through a single API.
OpenSERP started as an open-source project focused on making search engine data accessible without vendor lock-in. It was built to solve the complexity of maintaining reliable SERP scraping infrastructure across different engines, regions, languages, and anti-bot systems. Over time, the project evolved into both a popular open-source toolkit and a hosted SaaS platform for users who want reliable SERP access without managing browsers, proxies, or captchas themselves.
